Nanocrystalline silicon thin film growth and application for silicon heterojunction solar cells: a short review

Abstract

Doped nanocrystalline silicon thin films, in which silicon nanocrystallites are embedded in an amorphous silicon matrix, are emerging as carrier-selective contacts for next-generation silicon heterojunction solar cells.

Pengaruh Rapat Cacat Dangling-Bond Lapisan (p)a-Si:H Pada Kinerja Sel Surya Struktur p-i-n

“…Teknologi sel surya berbasis film tipis dapat dijadikan sebagai alternatif dalam pengembangan teknologi fotovoltaik (PV) didasarkan pada beberapa kelebihan yang dimilikinya, diantaranya fleksibel dalam penggunaan material dengan celah pita optik yang cukup lebar, secara alami tidak beracun, berbiaya rendah, temperatur proses rendah, tahapan fabrikasi yang sederhana, serta dapat diproduksi dalam skala yang besar [1]. Sel surya berbasis film tipis, seperti halnya silikon amorfus terhidrogenisasi (a-Si:H), nanocrystalline silicon (nc-Si:H), CdTe, CIGS, Dye-Sensitized Solar Cells (DSSCs), Organic Solar Cells (OSCs), dan Perovskite Solar Cells (PSCs) dikembangkan dengan biaya murah dan sumber bahan baku yang melimpah di alam, dimana dengan pencapaiannya sekarang sudah mampu bersaing dengan teknologi sel surya berbasis c-Si [2][3][4][5].…”

Utilization of CaF2/ITO Double‐Layer Anti‐Reflective Coating for Increasing the Efficiency in Rear Emitter SHJ Solar Cells

“…[ 9 ] In SHJ solar cell, the hydrogenated a‐Si thin film produces significant reflection losses due to its high refractive index. [ 10 ] The utilization of an optimized anti‐reflection coating (ARC) on the front side, a textured solar cell is important for reducing optical reflection losses and improving cell performance. [ 11,12 ] The application of transparent conductive oxide (TCO) when applied on the textured surface lowers the reflectance, thus enhancing the infusion of photons into the cell.…”

“…ITO is also utilized as an antireflection coating. [ 10 ] The double‐layer ARC (DLARC) has been designed to achieve minimum wide‐range reflectance and to minimize the reflection of light in the current limited wavelength spectrum of the cell. [ 19 ] In DLARC, the refractive index of the top film facing the air is the lowest and the subsequent layers are produced in ascending sequence of refractive index.…”

Analysis, Synthesis and Characterization of Thin Films of a-Si:H (n-type and p-type) Deposited by PECVD for Solar Cell Applications

“…Similarly, in [ 25 ], a study on n- and p-type doping of PECVD a-SiC:H obtained under silane starving plasma conditions with and without hydrogen dilution was presented. Some recent research reports [ 26 , 27 ] have provided a complete and comprehensive analysis of the thin-film amorphous silicon solar cell market focusing on revenue, growth patterns, market trends and the overall volume, along with a detailed analysis of all of the significant factors affecting the marketplace development of the industry and demand forecast to 2027. Moreover, a review on approaches to improve the power output of building integrated photovoltaic systems was presented in [ 28 , 29 , 30 , 31 ].…”
